Abstract
In a generator 120 in an electronic-controlled mechanical timepiece, the winding core 133b of a coil 134 arranged nearer to the perimeter of a base plate 2 is made shorter than the winding core 123b of a coil 124 arranged more inside. Accordingly, it is possible to make the area of an opening 2c can be made smaller in comparison with the prior art, and make the timepiece more small-sized by making smaller the outer diameter of the base plate 2 as keeping the distance D1 between the corner part of the opening 2c and the perimeter of the base plate 2 to the same degree as the prior art and thereby securing the strength of the base plate 2.
